Abstract
In a computer-to-plate system, printing plates are loaded from their shipping container onto a drum, where they are exposed by a laser. As the plates are packed with paper sheets between them, a paper removal system followed by a capacitance probe is used. The capacitance probe detects any paper remaining on the front or back of the plate. The plate is gravity loaded onto the drum and is resting on two contact points identical in position to the contact points of plate punching equipment. The orthogonal edge of the plate is detected electronically, in order to fully register the image to the plate. Magnetic clamps hold the plate to the imaging drum.
